NAME
sane-plustek - SANE backend for Plustek parallel port and LM983[1/2/3]
based USB flatbed scanners
DESCRIPTION
The sane-plustek library implements a SANE (Scanner Access Now Easy)
backend that provides access to USB flatbed scanners based on National
Semiconductor Merlin chipsets (LM9831, 9832 and 9833). If you're look-
ing for parallel-port support for Plustek scanner please refer to the
sane-plustek_pp backend.
SUPPORTED DEVICES
The Backend is able to support USB scanner based on the National Semi-
conductor chipsets LM9831, LM9832 and LM9833. The following tables show
various devices which are currently reported to work. If your Plustek
scanner has another Product ID, then the device is NOT supported, as it
contains an unsupported ASIC inside.

OTHER PLUSTEK SCANNERS
For parallelport device support see the plustek_pp backend.
The SCSI scanner OpticPro 19200S is a rebadged Artec AM12S scanner and
is supported by the Artec backend.
Only the National Semiconductor LM983[1/2/] based devices of Plustek
are supported by this driver. Older versions of the U12, the UT12, the
U1212 and U1248 (GrandTech chipset) are not supported.

CONFIGURATION
To use your scanner with this backend, you need at least two entries in
the configuration file
/usr/local/etc/sane.d/plustek.conf
[merlin-device] vendor-id product-id
device /dev/usbscanner
merlin-device tells the backend, that the following devicename (here
/dev/usbscanner ) has to be interpreted as USB scanner device. If ven-
dor- and product-id has not been specified, the backend tries to detect
this by its own. If device ist set to auto
then the next matching device is used.
The Options:
option warmup t
t specifies the warmup period in seconds
option lampOff t
t is the time in seconds for switching off the lamps in standby
mode
option lOffonEnd b
b specifies the behaviour when closing the backend, 1 --> switch
lamps off, 0 --> do not change lamp status
option invertNegatives b
b 0 --> do not invert the picture during negativ scans, 1 -->
invert picture
option cacheCalData b
b 0 --> do not save coarse calibration results, 1 --> save
results of coarse calibration in ~/.sane/ directory
option altCalibration b
b 0 --> use standard calibration routines, 1 --> use alternate
calibration (only non Plustek
devices, standard for CIS devices)
option skipFine b
b 0 --> perform fine calibration, 1 --> skip fine calibration
(only non Plustek devices)
option skipFineWhite b
b 0 --> perform white fine calibration, 1 --> skip white fine
calibration (only non Plustek devices)
option skipCalibration b
b 0 --> perform calibration, 1 --> skip calibration (only non
Plustek devices)
option enableTPA b
b 0 --> default behaviour, specified by the internal tables, 1
--> override internal tables and allow TPA mode (EPSON only)
option posOffX x
option posOffY y
option tpaOffX x
option tpaOffY y
option negOffX x
option negOffY y
x y By using this settings, the user can adjust the given image
positions. Please note, that there's no internal range checking
for this feature.
option posShadingY p
option tpaShadingY p
option negShadingY p
p overrides the internal shading position. The values are in
steps. Please note, that there's no internal range checking for
this feature.
option redGamma r
option greenGamma g
option blueGamma b
option grayGamma gr
r g b gr
By using these values, the internal linear gamma table (r,g,b,gr = 1.0)
can be adjusted.
option red_gain r
option green_gain g
option blue_gain b
r g b These values can be used to adjust the internally detected
gain values of the AFE for each channel. The range is between 0
and 63.
See the plustek.conf file for examples.
Note:
You have to make sure, that the USB subsystem is loaded correctly and
the module scanner has been loaded too. To make this module recognize
your scanner, you might have to add the following line to your
/etc/modules.conf :
options scanner vendor=0x7b3 product=0x17
If you're not sure about the vendor and product id of your device, sim-
ply load the USB subsystem and plug in your scanner. Then do a cat
/proc/bus/usb/devices and look for the scanner.
Alternatively, the backend is able to access your scanner via libusb.
You might use sane-find-scanner to check that you have access to your
device.
Note:
If there's no configuration file, the backend defaults to device auto
FILES

The backend configuration file
/usr/local/lib/sane/libsane-plustek.a

CONTACT AND BUG-REPORTS
Please send any information and bug-reports to:
Plustek Driver Mailing List <plustek@linuxhacker.org>
or directly to:
Gerhard Jaeger <gerhard@gjaeger.de>
Additional info and hints can be obtained from our
Mailing-List archive at:
http://www.linuxhacker.org/cgi-bin/ezmlm-cgi/3
or directly from the projects' homepage at:
http://www.gjaeger.de/scanner/plustek.html
To obtain debug messages from the backend, please set the environment-
variable SANE_DEBUG_PLUSTEK before calling your favorite scan-frontend
(i.e. xscanimage).
i.e.: export SANE_DEBUG_PLUSTEK=20 ; xscanimage
The value controls the verbosity of the backend. Please note, that val-
ues greater than 19 force the backend to output raw data files, which
could be rather large. The ending of these files is ".raw". For prob-
lem reports it should be enough the set the verbosity to 13.
KNOWN BUGS & RESTRICTIONS
* The driver does not support these manic scalings up
to 16 times the physical resolution. The only scaling
is done on resolutions between the physical resolution
of the CDD-sensor and the stepper motor i.e. you have a
600x1200 dpi scanner and you are scanning using 800dpi,
so scaling is necesary, because the sensor only delivers
600dpi but the motor is capable to perform 800dpi steps.
* Plusteks' model policy is somewhat inconsistent. This
means, they sell technical different devices under the
same product name. Therefore it is possible that some
devices like the UT12 or U12 won't work - please check
the model list above and compare the product-id to
the one your device has.
* Negative/Slide scanning quality is poor.
